Re: Spikes!
PHD recommended min limit for image scale is 0.5" so i would bin 2 at a minimum all of your calibrations are problematic here's a typical example the calibration run should be 25 pix across 12 steps,

Re: Spikes!
Yes, using my 178 it should be 0.35 when using the OAG. I have binned it in the past but found that it didn't seem to help, so I just leave it native. Using my 1600 it should be 0.55 according to
Re: Spikes!
Jamie is your pixel scale really 0.34"? the calibration looks really wonky too (or as a result) jamie.amendolagine@...> wrote: -- Brian Brian Valente portfolio brianvalentephotography.com

Re: Spikes!
Here it is. I believe that from 19273 seconds onward the scope was on the East side, and before that point it was on the west. Jamie

I'll do that now. My plan for tonight is to switch to the guide camera where everything was working fine a couple weeks ago, before the recent rains. Jamie

Re: Spikes!
Michael, you are awesome! So I've already switched my guiding to use the main camera, a ZWO ASI 1600MM Pro, from the guide camera, which is a 178MC. So far things are looking much better, but I'm

Re: Spikes!
Dear Jamie, Let's try to chase the cause...a couple of simple things to try: 1. Balance the mount in RA and DEC. 2. Now unbalance the RA: Wrap a rope or cord around the RA axis so the string drops to

Re: 76 second RA periodic error fixed with Belleville washer
That additional computer interface is on my ever growing ToDo list! Actually, you can just use the ammeter to tell if the mount is balanced, which you tell by slewing CW and CCW on an axis...best with

Re: 76 second RA periodic error fixed with Belleville washer
Michael, Does your ammeter just give reading, or can you get an amps vs. time plot? I was thinking graphing the data might be a way to show potential resistance to motion as the worm turns against the

Re: Still working out polar alignment on my mount
Jeff, Sounds like you need to reset the mount limits. Personally I use the MI-250 default settings which are the most conservative, or give the widest margins. There is a way set set your personal

Still working out polar alignment on my mount
